The correct answer is to create a Conditional Access policy with the sign-in risk condition set to High and Block access, and then configure alert notifications in Identity Protection. This works because the Conditional Access policy enforces the block at the authentication gate, preventing the user from completing the sign-in, while the Identity Protection alert system independently notifies administrators of the high-risk event. On the MS-102 exam, this scenario tests your understanding of how Conditional Access policies handle real-time risk enforcement, whereas Identity Protection handles post-event monitoring and alerting—a common trap is thinking that a single policy or alert does both jobs. Remember the split: Conditional Access blocks the door, Identity Protection rings the bell. A useful memory tip is “Block with CA, notify with IP,” keeping the two responsibilities distinct in your configuration.
MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization has a Microsoft 365 tenant with 10,000 users. You are configuring Microsoft Entra ID Identity Protection to detect risky sign-ins. You need to ensure that when a sign-in risk level of 'High' is detected, the user is blocked from signing in and an administrator is notified. What should you configure?
Create a Conditional Access policy with 'Sign-in risk' condition set to 'High' and 'Block access', and configure alert notifications in Identity Protection
This combination blocks high-risk sign-ins and sends notifications.
B
Create a user risk policy in Identity Protection to block high-risk users
Why wrong: User risk policy applies to user risk, not sign-in risk.
C
Create an MFA registration policy in Identity Protection
Why wrong: That policy enforces MFA registration, not blocking based on sign-in risk.
D
Enable Security defaults and configure notifications
Why wrong: Security defaults block high-risk sign-ins but do not provide granular notification configuration.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Conditional Access policy with 'Sign-in risk' condition set to 'High' and 'Block access', and configure alert notifications in Identity Protection
Option A is correct because it combines a Conditional Access policy that blocks access when the sign-in risk level is 'High' with an alert notification configured in Identity Protection. The Conditional Access policy enforces the block at the authentication level, while the Identity Protection alert ensures administrators are notified of the high-risk sign-in event. This directly meets the requirement to both block the user and notify an admin.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse user risk policies (which target compromised accounts) with sign-in risk policies (which target risky authentication sessions), leading them to select Option B instead of the correct combination of Conditional Access and alert notifications.
Detailed technical explanation
How to think about this question
Under the hood, the sign-in risk level is calculated by Microsoft Entra ID Protection using real-time signals such as impossible travel, anonymous IP addresses, and leaked credentials. The Conditional Access policy evaluates this risk during authentication and can enforce a block before the token is issued. Alert notifications in Identity Protection are configured via the 'Notifications' blade, which sends email to specified administrators when a risk event is detected, ensuring the admin is informed even if the user is blocked.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
